Perhaps you should try some spelling variations:
te sach » toc sach
nang ma » tang ma, sang ma, nang cao
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, thuc van
xuc ban » duc ban, cuc ban, quoc ban
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang ma) or (lang xa)) hoi. hieu ve cam ((xuc van) OR (xuc ban)) hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang ma) OR (lang xa)) hoi. hieu ve cam ((xuc van) OR (xuc ban)) hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang ma) or (lang xa)) hoi. hieu ve cam ((xuc van) OR (xuc ban)) hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang ma) or (lang xa)) hoi. hieu ve cam ((xuc van) OR (xuc ban)) hanh vi cua tre*.
